" The present invention""pertainsy to .bedsprings andy similar cushioning structures,

its prime object beingy the .provision or production of a construction `ofl this character i' wh ich isfeconomical to manufacture, and'vvhijc'h possesses" livhich is simple in structure,

particularly advantageous functional qualities, especially a high, degree of `resiliency and flexibility and capability iiexure to readily and easily itself to the contour of the body cupant.

To this end, in the preferred embodiment of the invention, the bed-spring'has a inattress or cushion bearing portion composed of a plurality of'parallel, springsupported, flexible, metal strips or ribbons yieldingly associated together and in part su v transverse 'springs equipped witi clips or the like through which the metal strips or ribbons may readily slide, whereby to give to the structure that capacity for give or yield of parts to afford maximum comfort to the person occupying the spring.

To permit those skilled in this art to have a full and complete understanding of this invention, both from structural and functional standpoiiits, in the accompanying drawing, throughout the several views of `which like reference characters have boeg have. illustrated two desirable embodiments of the invent-ion in satisfactory commercial form.

ln this drawing:

Figure 1 is a fragmentary plan View of a corner portion only of a bed-spring incorpoi-ating one embodiment of the present invention;

Figure 2 is an enlarged cross-sect1on on line 2-2 of Figure 1;

' Figure 3 is a similar cross-section of a modified construction; and Y Figure 4 is a fragmentary plan view of a small portion of the structure rdepicted in Figure 3. Y

Inasmuch ture are alike, and the two side portions of the same are identical except reversed, it is merely necessary to illustrate and describe a small corner section of the bedspring in order to give a fullunderstanding of the structure as a Whole. y

The bed-spring at each end: includes the usual end-bar 11 supported on brackets, not

accommodate of the ocof localizedv ported by as both ends of the bed struc- D come and ygo to give the appliance a satisfac- ,showin and each ofthe longitudinal borders ring has a flat, marginahmetal Y strip' 12 supported at eaclr end bythe corresponding 'end-bar A11 by meansL of a pair "ofcoiled"or"helical ysprings k13, 13 having of thebedsp terininalhooks taking into holes of each.

Thefmain portion of the mattress or cushion 'sustaining 1 part "of the bed-spring includes ap'lurality of parallel, spaced, longitudinally-disi'iosed, metal strips, straps or it.' Vbands 14, 14n preferably possessing a substantial degree of resiliency and capable of material. lexure, each end of each vof these bands or straps being mounted on the corresponding bed-spring end-bar by a coil contractile spring 15 having hooks at its eX- tremities extending into apertures of the parts mentioned.

.It is necessary'to unite or join such strips or straps 12 and 14 together at intervals to 'f moi'e adequately support them and to prevent them froin unduly separating or spreading apart, and, in the particular embodiment ofthe invention illustrated inFigures 1 and 2, this is kaccomplished by the employment of transverse, coiled'springs 1G, 16 between the bands or strips and connected together by clips 17, 17 slidingly accommodating the straps or bands 14 and each supplied at' its opposite ends With eyes or loops 18 yfor association With the ends of the corresponding springs, the terminall springs 16 of each transverse or cross row each having one end connected directly to the marginal or border member 12, this being easily accomplished by hooloends of the springs extending down Vthrough apertures in the element 12.

lt Will bc understood that the members 12 and 14C are not only more or less resilient in themselves, but they are yieldinglysupi ported yat their ends by the coiled springs 13 and 15 and they are crosswise associated together yby the intermediate or intervening springs 16, the bands or straps being free to Slide through the members joining the ends of adjacent cross springs so that the several parts of the structure may yield and tory high degre of resiliency and comfort for the occupant.

In Figures 3 and 4 a somewhat different structure is Shown, all of the parts being the same, except that each clip or band-sustaining element 17 has been replaced by a pair of Wire links 21 and 22, the one above the lll) strap or band 14 and the other below it, as is clearly indicated in Figure 3, the two ends of each link being supplied With eyes o1' loops 23 through which the hook ends of the coil springs 16 take to unite the parts together.

Both styles of structure are satisfactory, but the one depicted in Figures 1 and 2 has the advantage of incorporating fewer parts and possibly an advantage from an economical manufacturing standpoint.

T hose trained in this industry Will readily understand that the invention is not limited and restricted to the particular embodiments presented and many mechanical changes may be made in these. Without departure from the heart and essence oi'f the invention, as deined by the appended claims, and Withoutthe sacriiice of any material advantages accruing from the employment of the invention.

I claim: s

A bed-spring` composed in combination solely vof end-bars, lengthwise-disposed marginal straps supported on said end-bars.l parallel spaced longitudinallyarranged flexible metal strips, coiled springs connecting the ends of said strips to said end-bars, and a series of parallel, straight, transverse rows of articulated members connected to said marginal straps and composed of alternating coiled springs and clips rockingly connected together end to end with said clips slidingly accon'imodating and in part supporting said flexible met-al strips.

Inivitness whereof l have hereunto set my hand.
